Use a primary standard to determine an unknown concentration using an acid-base titration. Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as a primary standard. It has the unwieldy formula of KHCRH4O4. This is often written in shorthand notation as KHP. If 34.47 mL of a barium hydroxide solution are needed to neutralize 1.279 grams of KHP, what is the coicentration (mol/L) of the barium hydroxide solution?
